Analysis of common problems
Problems
The number and concentration of particulate matter in the air
quality.
Data is not accurate
Analysis
1. Particulate matter data has a certain spatial and temporal nature,
sampling do not in the air flow velocity fluctuations or particulate
matter changes obviously, if necessary, you can sample data multiple
times
2. No data display of the number of particles in the air and
concentration quality
Problems
Manual mode when not pressed sampling
Battery power is too low to start the sensor work
Temperature and humidity are not accurate
Analysis
1. Temperature and humidity sensor sampling window with debris, dirty
Problems
1. Ventilation window is blocked by something
2. Do not turn on
Analysis
1. The battery is dead or damaged, powered by USB socket, if you can
turn on and the upper right corner of the power grid has changed, is
the battery is dead, such as no change only shows OK icon. Indicates
that the battery has been damaged.
2. The battery +/- polarity is reversed, it should be noted that one end
of the battery without a protruding contact point is the "-" pole, and
the end with a protruding contact point is the "+" pole. Can refer to
the following chart
